Environmental diseases related to cadmium exposure primarily develop owing to industrial wastewater pollution and/or contaminated food. In regions with high cadmium exposure in Japan, cadmium accumulation occurs primarily in the kidneys of individuals who are exposed to the metal. In contrast, in the itai-itai disease outbreak that occurred in the Jinzu River basin in Toyama Prefecture in Japan...

According to Paracelsus (1493-1541) everything from this planet is poison, only the dose makes the poison to be harmless. Even the essential elements for life support are toxic for all organisms in high amounts. Mercury, cadmium, metalloid arsenic and lead were responsible for poisoning and death of many humans and life forms from this planet for centuries. Cadmium forms different compounds tha...

conclusions according to the high efficiency of cadmium elimination by tea waste, this approach is applicable as an efficient and affordable trend to remove cadmium from aqueous solution without any chemical or physical pre-treatment. background heavy metals pollution is a serious threat to environment and human health. therefore, it is vital to find an effective method to remove heavy metals f...

Owing to its unique nutritional and immunological characteristics, breast milk is the most important food source for infants. But, children are at greater risk for exposure to environmental toxicants from breast milk. The aim of this study was to evaluate the influence of environmental pollution on essential and toxic element contents of breast milk and determine the risky locations in our popu...

Marine intertidal mollusks, such as oysters, are exposed to multiple stressors in estuaries, including varying environmental temperature and levels of trace metals, which may interactively affect their physiology. In order to understand the combined effects of cadmium and elevated temperature on mitochondrial bioenergetics of marine mollusks, respiration rates and mitochondrial volume changes w...

heavy metal pollution in aquatic ecosystems has become one of the global issues. mollusks such as clams can be used as bioindicators and biomonitors of heavy metal pollution in these ecosystems. in fact, mussels and oysters have been widely used for this purpose. in this study, the concentrations of cadmium were measured in soft tissues of rock oysters )saccostrea cucullata( collected from two ...

We studied changes in macrobenthic communities following the environmental clean-up of metal-polluted (cadmium, nickel, and cobalt) sediments in Foundry Cove, a small inlet within the Hudson River estuary of New York. We used a BACI-style experiment to test the hypotheses that high levels of cadmium in sediments change macrobenthic assemblages relative to unpolluted areas, and removal of metals...

Pollution of the aquatic environment by heavy metals has become a worldwide problem. Most heavy metals exhibit toxic waste on aquatic organisms. Cadmium (Cd) is a highly toxic metal which affects aquatic organisms acutely and chronically. Planktonic calanoid copepods are the secondary dominant producers of pelagic ecosystems and play a considerable role in the transfer of energy and organic mat...
